FB goes against silicon valley's zeitgeist and it gets disproportional hate. IMO, all social media is toxic and it has done more damage to the society than benefited ... but the biases are very much evident in how each service is perceived by the larger tech community. FB also did many eggregious things, no doubt. Election interference, etc.
Meanwhile, Tiktok is HN's darling.
Another thing is Twitter has become de facto channels for official communications of government bodies. How do you access these official channels? With a phone number of course when you try to register an account - which is required. Twitter has destroyed the world by coaslescing social media, outrage tactics, government bodies into one hot boiling soup of toxins.
